The moneypot in the Stuart Gallery (left hand picture) dates from 1650 to 1660 and is an example of Wrotham Ware. This is a form of slipware, a type of pottery that flourished in many areas of England in the 17th and early years of the 18th century. Essentially it is red or buff earthenware, decorated with a white or coloured slip (diluted clay) that contrasts with the body. A yellowish lead glaze is characteristic.
It is named after the village of Wrotham in the Weald of Kent where, from 1610 to about 1710, several potters made pots and jugs by hand or with a wheel, using local surface clay and applying a lead glaze before firing.
The tyg (drinking mug) illustrated on the right is in the Nelson-Atkins Museum of Art, Kansas, USA and is typical of the slipware made at or near Wrotham. These pieces are often dated and have the potter’s initials. These days examples in good condition can fetch several thousand pounds at auction. In 2011, Christies sold a collection including a 4-handled tyg similar to the one illustrated here. It was dated 1643 and sold for £7,250.
